"automatically centering and quadding lines of matrices prior to thecastingoperation.

Machines of the type with which this invention 7 is employed, such asLinotype? machines, as- "semble matrices to form a line of print andmove a complete line to a casting position where the matrices arejustified to the desired measure 'between jaws of a vise prior tothecasting operation.

When a short line of type is formed, it is necessary for the operator tofill the line with quads in orderthat the line will be held tightlybetween the jaws of the vise during the casting and thereby prevent flowof the molten metal between'the matrices. Similarlyjt is necessary fortheoperator to fill a line with the proper number of quads on each sideof the line of matrices when a line is to be centered, as in theheadlines of a newsp p i 'j Some of the more modern type castingmachines have been provided with apparatus which allows automaticcentering and quadding of the matrices. It is necessary,-however, tocompletely rebuild the vise mechanism of the older machines in order toinstall the automatic quadding and centering attachments heretoforavailable.; In addition to the high cost of thePl'iOl attachments, itwas necessary to take the machine out of operation for extended periodswhilethe attachment wagbeing installed. a a I I r I It is an object ofthis inv ention to providean automatic spacing attachment for typecasting machines which may be easily and quickly installed on old lineassembling typesetting machines.

It is also an objectof this invention to provide an automatic quaddingattachment for type castsing machines in which the required quadding tofill out either end ofitheiline for the setting of 'type around cuts;for advertisement and comanercial printing composition; for fillingout'ends -of paragraphs, etc., is accomplished by movement Anotherobject of this invention is to provide an attachment which will allowautomatic center;-

ing of a short line of type.- I I A further object of thisinvention isto provide an attachment which will automatically indent short lines oftyp andjustify the short line at the desired measurement.

Still another object of this inventlonis to vide an attachment tofacilitate the changing 2 An additional object of this invention is topro.- vide an attachment for releasing the pump stop, permittingcastingof. the line, from a movable right vise jaw. 1

..With these and other objects in view as will become apparent in thefollowing detailed description, this invention resides in an attachmentfor a line assembling and type casting machine in which the matrices areheld in the casting position between movable jaws which may be set at adefinite pica or random measure. A selector control is provided to allowthe centering or quadding to the left or right as is desired by theoperator of the machine of short assembled lines. of

Figure 11 is a plan view of the control and braking means therefor withparts of the control broken away. The attachment comprising thisinvention may be installed on a conventional"Linotype" line forming andcasting machine andreceives power for its operation from that machines:InFigure 1 thefirst elevator of the type casting machine is shown inphantom and indicated... by reference numeral I. Directly in front ofthe elevator is an operating barZ which slides horizontally in a casing3 to move a driving rack 4 secured to one end of the operating bar 2.The rack 4 engages a pinion gear 5, illustrated in Figure 8, whichdelivers the power necessary to move the jaws of the visa through asuitable gearing mechanism hereinafter described. The motive power foroperating bar 2 is derived from a spring 6 connected by means of a line1 passing over pulleys 8 and to the elevator I. As the elevatordescends, it stretches the spring 3 which exerts a force on theoperating bar 2 and the driving rack 4.

The operating bar 2 is held in a normally cocked. position by means of adetent I0, illustrated in Figure 10, which engages a catch II on aplunger I2 slidable vertically within the casing 3. The

plunger 12 is urged upwardly byia compressed I spring l4 bearing againstthe base of the casing 3 in order that the side of the catch H willengage the detent It. The upper end 13 of the plunger is stepped forcontrol of the operation of the plunger as hereinafter described. Achannel I5 extends across the face of the plunger [2 immediately abovethe catch H to allow the detent If) on the operating bar 2 to pass whenthe plunger 12 is depressed.

A guide It is slidably mounted on the upper surface of the casing 3directly behind the plunger [2 in the manner shown in Figure 1. Theguide 16 has a concave upper surface for the reception of a guide pin I1which depends from an arm 18 best illustrated in Figure 2. The arm I8 isfree to pivot horizontally about a bolt l9 which supports it frombracket 20 secured to the elevator l. A tripping finger 22 is alsoconnected to the arm l8 and extends downwardly therefrom substantiallyparallel to the guide pin 11. The guide pin 11 engages the upper surfaceof the guide [6 to swing the arm l8 horizontally about bolt I9 andthereby fix the position of the tripping finger 22 to control theoperation 01' the mechanism in the manner hereinafter described.

An arm 23 extends laterally from the righthand side of guide 15 (seeFigures 1 and 3), and is connected with a lever 24. The lever 24 is inturn linked with an arm 25 which pivots about a pin 26 supported by theframe work 21 attached to the Linotype machine. Arm 25 is slotted at 28,remote from the lever 24, for operative connection with a rod 29 whichslides horizontally in its support 33. In alignment with the rod 29 forengagement therewith is an expansion rod 32 which is operativelyconnected to the assembler, indicated diagrammatically by 3|, of theline forming and type casting machine to move to the left, in Figures 3and 4, to engage the rod 29 when a line is fully assembled. Expansionrod 32 has a slide clamp 33 on its end adjacent rod 29 to allowadjustment of the effective length of the rod 32 and provide anexpansion allowance in the assembler as will become apparent in thedescription of the operation of the attachment comprising thisinvention. The slide clamp 33 has a snap fitting which engages grooves34 on the expansion rod 32 to hold the slide clamp 33 firmly in place.The grooves 34 are preferably spaced apart a diStance equal to a picameasure for accurate control of the expansion allowance .in theassembler. Aspring 35 is attached to the side'of guide 15 opposite arm23 and to the frame 21 to the left of the guide 16 in Figure 1. Thespring 35 under tension and constantly urges guide 16 to 4 wards theleft and, consequently, rod 29 toward slide clamp 33.

Movement of the guide IE to the left is prevented by a finger 31 whichextends from the side of the guide directly above the spring 35. Thefinger 31 engages a cam 38 mounted on a rod 39 connected to a flipper 40which is conventional on Linotype machines for controlling the downwardmovement of the elevator when the auxiliary characters on the matricesare to be cast. When the flipper is turned to the position for castingof the auxiliary characters, the cam 38 allows the spring 35 to draw theguide It to the left of its normal position.

,In .order to prevent movement of the guide after its position has oncebeen fixed for the casting of a single line of type, a brake 42 ispivotally mounted on the frame 21 and bears against the back surface ofthe guide It as shown in Figure 11. A leaf spring 43 extends from theframe 21 to the end of the brake 42 remote from the guide l6 andconstantly urges the brake against the guide. The brake 42 exerts asmall force against the guide It which allows it tomove under thepositive force exerted by rod 29 through linkage 23, 24 and 25, but doesnot permit the force of spring 35, or vibration of the Ina-- chine, tomove the guide [6. A head 44 (see Figure 11 on the brake 42 near itsconnection with the spring 43 extends backwardly beyond the frame 21 toengage a cam 45 which is secured to the elevator. As the elevatorascends,- the cam 45 engages the head 44 and releases the brake 42- toallow the spring 35 to return the guide [6 to its normal position.

The cam 45 extends diagonally across the elevator I of the line formingand type casting machine in the manner illustrated in Figure l andengages a roller 46 which is secured to the operating bar 2. As theelevator ascends, the cam 45 engages the roller 46 to move the operatingbar to the right to the cooked position in which the detent ID willengage the catch H and hold the operating bar 2 in place. The beveledsurfaces of the detent I0 and the catch ll allow free movement of theoperating bar to the right by compressing the spring Hi. However, oncethe detent ID has passed over the catch ll, spring 14 lifts the plungerand locks the operating bar 2 securely in place. Movement of theoperating bar 2 after the catch has been released may be limited by anadjustable stop 41 which is preferably mounted in a block 48 on thefront of the casing 3. The block 48 on the front surface of the casing 3is equipped with anysuitable clamp 49 for holding the stop 41 tightly atany desired position. The stop 41 is graduated in pica measure on ascale 50 to allow accurate adjustment of the movement of the operatingbar 2 and, consequently, of the jaws of the vise. If the line is to beof random length, stop 41 should be moved to the left where it will notbe engaged by operating bar 2 and will not limit the movement of thatbar.

The operating bar 2 is connected to the rack 4 by means of any suitableadjustable connection indicated by 52. The connection 52 allowsadjustment of the rack 4 with respect to the operating bar 2 in orderthat the scale 50 on stop 41 will indicate accurately the movement ofthe jaws of the vise. Referring to Figure 8, the rack 4 engages a pinion5which is secured on a shaft 53. Shaft 53 is free to turn in either'direction, and is supported by the walls 54 of the housing indicatedgenerally by 51 enclosing and supporting the driving mechanism. The'shaft'53 isfree, to slide axiallyas well as rotate in the housing; Aspur gear 55 and a second pinion gear56' are also secured to the shaft53 for rotation therewith. The spur gear 55 engages a second spurgear 51of the same diameter which'is mounted on "a shaft 58 parallel to shaft53 to'rotate the shaft 58 in a direction opposite the rotation of shaft53. The shaft 58 is also supported by the walls 54 of the housing in amanner'pe'rmitting axial move ment as well as rotation. A pinion'gear 59hav ing the same diameter as pinion gear-56 iskeye'd to the shaft 58 forrotation therewithj 1 Shaft 58 extends through Wall 54 of'the hous ing5| for a short distance and has a head 66 on its end spaced from thehousing. A compressed spring 62 rides on the shaft'58 andbears againstthe head 66 and the wall 54 of thGhOllSlIli-Zifil and urges the shaft tothe left to the "normal position shown in the drawings. The end'of theshaft 58 remote from the head 68 'has a dial 6 3fwith a scale 64 on itsface attached-thereto by means of a set screw 65. I A collar 56 rides onthe shaft-581cctween the dial 83 and the walls 54 of the housing 5| tolimit the axialmovement of the shaft towards the left in Figure 8resulting from the compression of the springBZ; s s Referring to Figure5, a rack 61 is'slidably supported in tracks 69 in the housing 5|directly below the pinion gear 59 andmeshes therewith. The rack 61 isconnected to a base 69 of a jaw 16 of the vise inwhich the matrices areheld during thec'asting operation. The base 69 is secured to the rack 61by any suitable means indicated by reference numeral 1| in Figure 3. The,jaw10 is rigidly secured to the base 69 which is free to slidehorizontally'in the conventional opening, not shown, in the vise head ofthe L inotype.

The selectorrod- 11 is connected at its end remote from the selectorhandle 19 to a linkage 86 joining the rod to a control bar 81. Referringto Figure 8 of the drawings, it will be noted that the control'bar'81 isU-"sh'aped and bears against both ends of the, shaft 53 to move it alongits axis in the housing 5| to the desired position.

The driving mechanism is shown in Figure 8 with the indicator handle inthe center position. It-Will' be notedthat the pinion 5 is centeredabove the rack 4 and is approximately three times as wide as rack A. Thespur gear 55 is approximately twice as wideas' thespur gear 51 withwhich it Pinion'gear 56 engages a rack12 similar to rack 61 which alsoslides horizontally intracks13 in the housing 5| directly belowthe'p'inion 56.- The rack 12 maybe connected directly to the-base; 14,or the base and rack may befjoined by a connecting rod 8| as is shown inthe drawingskfnny suitable means, such as 16, are'provided'forconnecting the base 14, with the rack which will allow adjustment of thebase relative to thepositionof the rack 12.

Referring to Eigurel offtheidrawin gs, afselector rod 11 is supportedby, a trunnion 18 mounted on the upper surfaceof the housing 5|jat oneend andby frame 21'at the other end. A selector handie 19 is keyed tothe rod 11 at the end adj'a'cent the; frame, 21; The; indicator {handle,19;,move's wardly from the handle by afspring, not hown, within thehandle for insertion in thelape. ures theselectorscale 80L Aperture 82corresponds It is preferred that racks 4, 61, andi1'2 andpinion firmly;place "just prior to "the" justification of meshes andtherighthand facesof the two spur gears are in alignment when the indicator is inthe'center position. The pinion gears 56 and 59 are approximatelytwice'as wide as the racks 12 and 61 with'which theymesh. When theindicator is in the center position, the left face of pinion gear 56 isin alignment with the left edge of rack 12. The right face ofthe piniongear 59 is in alignment with the right face of rack 61 when the shaft 58is in thenormal position to which it is urged by the spring62; I,

' In the center-positionillustrated in Figure 8, any movement of therack 4 will turn the pinion 5 and cause movement of both racks61 and 12through the intermediate gears. If the selector handle is changed to theright quadding position, the shaft 53 will be moved to the right by thecontrol 81 to disengage-thepinion gear 56 from the rack 12. Any movementof therack 4 will then be transmitted through the pinion gear 5, spurgears 55 and 51, and the pinion gear 59 to the rack 61 to move the leftjaw towards the stationary right'jaw of the vise. If the indicatorhandle 19 is moved to the left quadding position, the shaft-53' is"moved to the left and spur gear 55 is moved out of engagement with spurgear 51. Movement of the rack 4 is then transmitted through pinion 5 andshaft 53 .to pinion gear 56 I which drives the'rack 12. The rack 12moves the right jaw of the vise towards the left jaw for-the leftqua-dding operation. The disengagement of the-spur gears 55 and 51allows the left jaw to remain stationary. r

The measure'between the 'jaws of the vise 'vvhen'ith' operating bar isin the. cooked position may be adjusted by means of dial 63 and shaft56'. V The selector control handle 19 is set-at the center positionandthe dial 63 is pulled to the right," "in" Figure 8,compressing'spring 62; The movement of the shaft 58 to the rightdisengages spur gears55 and 51 and allows rotation of pinion gear 59while pinion'gear 56 remains stationary.; Dial' 63 may then be turned,thereby turning pinion gear 59' and moving the rack 67 to adjust theleft jaw of the viseto'the desired inefasure." Apointer 8:8 e'xtends"across the scale 64 to indicate the measure at which the jaws are beingset. *Rel'eas'e of the handle 63 will allow [the spring 62 'to returnthe shaft 58 to the normal position, and thepoin'te'r '88 will indicatethe measureofthe line. I

In"ord'er" to allow accurate alignment of the 'ty pe atan exact picameasure during the castingfoperation, it isnecessary to' lock theijawsthe line of type and hol'd 'them firmly "in place during thejustification. For this purpose the I racks61 and 12 are provided withratchet teeth 89 having a pica'or one half pica'spac'ing along theirbottom surface. Pawls, 90-. and 9I are positioned directly below theracks 61 and I2, respectively, and are. adapted f'orvertical movement inthe housing 5|. The pawls 99 and 9i move upwardly between the tracks 68and IE on which the racks travel.

Referring to Figure 9 of thedrawmgs in which pawl 99 is illustrated, asliding member 95 comprising the main body of the pawl moves obliquelyupward in diagonal channels 95 in the housing 5I. A latching member 96extends vertically upward from the upper surface of the slid ing member94 and is urged upward from sliding member 94 by a compressed spring 91.The upper surface of latching member 99 is serrated to form ratchetteeth 98which will engage the ratchet teeth 89 on the lower surface ofthe rac 67. For further support of the latching member 99, a verticalshoulder 99 is provided extending upwardly from the sliding member 99and against which latching member 96 slides. A secnd shoulder I99extends horizontally at the lower end of the pawl 99 to bear against thehousing I and limit the upward movement of the pawl. I

Referring to Figure "1, means are provided to force the pawls againstthe rack when the rack is disengaged from the driving means to hold thejaw in a definitely fixed position. A lug I92 extends outwardly from thepawl 99 into a channel I93 in a bearing block I94. The bearing block I94is mounted upon a locking rod I95 which is slidable vertically throughthe housing 5| to a position above the top surface of the housing. Thepawl 9I, which is similar to the pawl 90 in construction with theexception that the diagonal movement is in the opposite lateraldirection, is supported in a similar manner by a locking rod I91 and abearing block I99. .A releasing spring I96 is positioned on rod IiiI between the upper surface of the bearing block I98 and the bottom of thehousing 5I to constantly urge the bearing block, and, consequently, thepawl 9|, downward. A spring, not shown but similar to spring I99 andobscured by it in Figure 5, constantly urges the bearing block I94downwardly. A guide rod I99 is provided between the two bearing blocksfor further support of the blocks as they move vertically.

Locking rod I95 passes between the. prongs III! and H2 of a bell crankH3 pivotally supported on the top surface of the housing 5 I. The bellcrank I I3 is connected bysuitable linkage indicated generally by III;to the selector rod II. When. the selector handle I9 is turned to theleft quadding position by ture 34, the bell crank lever I I3 is turnedand the prongs III) and H2 bear against a nut H! on the upper end of thelocking rod I95. The bell, crank lever lifts the rod I95 and bearingblock I94, which engages by lifts the pawl 99. As the pawl movesupward,the teeth 98 in the latching member 96 contact the teeth 89 on the rack.Further upward movement of the pawl 90 will result in compression of thespring 91 and the latching member 96 will slide laterally until ratchetteeth 98 and 89 are meshed. Perfect fitting of the vratchet teeth isinsured, and the left jaw I0-of the vise is held firmly in place. Asmentioned abovewhen the indicator handle I9 is set for. the leftquadding position, the spur gears and 5I..are disengaged and the rackI9. is then free to move independently of the rack 61.

, .A similar locking mechanism is provided for inserting pin .85in'aper,-

the lug I92 and therelocking the right jaw in the right quaddingposition. A bell crank lever H8 has prongs H9 and I20 extending beyondthe locking rod IIII. As the selector handle I9 is turned to the lockingposition, a linkage indicated generally by I2I rotates the bell crank H8and lifts the locking rod IOI to lock the right jaw I5 in place. Whenthe indicator is positioned for right quadding, the bell crank I I3 islowered and releasing spring I96 drops pawl 99 from engagement with theratchet teeth on the bottom of the rack 61. The pinion gear 56 isdisengaged from the rack I2 and the spur gears 55 and 51 mesh to drivethe rack 61 independently of the rack I2. v

Both jaws must be locked prior to line justification and during casting.If left or right quadding is being done, one jaw is hand locked in themanner already described; if centering, neither is hand locked; thedevice will lock either or both as required before the castingoperation. For this purpose bars I22 and I23 are pivotally supported atone end by a hanger I24 which depends from the housing 5|. The bars I22and I23 are positioned directly below the locking rods I05 and I0! andbear against the lower ends of the rods to control their downwardmovement. Justification springs I25 are suspended from studs I21protruding from the housing 5i, and are attached to the bars I22 and I23near their end remote from the pivotal attachment to hanger I24. Thesprings I25 are normally under tension and constantly urge the bars I22and I23 upwardly. The force exerted by springs I25 is greater than thatexerted by releasing springs I99 and I98 and will overcome the force ofthose springs to move the pawls into position to lock the racks 61 andI2 when the bars are free to move upward.

When stop 41, Figure 1, previously described, is not employed to controljaw movement and allow lines to justify at an exact pica measure, eitheror both jaws will travel until resisted by a line of matrices or by oneanother. In such case pawls and 9I rise in diagonal channels to engageracks B1 and I2 as hereinbefore described and wedge the jaws to therandom dis- .tance necessary to justify the line and release the pumpstop, whether or not spacebands are in the line.

A connecting rod, indicated by reference numeral I29 in Figure 5, isconnected to the end of each of the bars I22 and I23 remote from theirattachment to hanger I24. The connecting rods I29 are secured at theirlower ends to the vise closing lever I30 (see Figure 1) which is part ofthe line assembling and type casting machine. Generally it will bepreferable for the connecting rods I29 to be slotted at I3I at theirupper end for the reception of a pin I32 engaging the upper "end of theslot and the bars I22 and I23. The connecting rod I29 will then preventupward movement of the bars I22 and I23 and thereby allow releasingsprings I95 and the releasing spring on the rod I05 to maintain thepawls in the unlocked position when the vise closing lever is in itsdepressed position.

At the time the vise closing lever rises prior to the justification' ofthe assembled matrices, the connecting rod I29 will rise and allow theforce exerted by the springs I25 to move the bars I22 and I23 upwardly.The upward movenjient of bars I22 and I23 forces the locking rods I95and 'Iol'upward. The pawls 99 and 9i are thereby moved upward intoposition to engage the ratchet teeth 89 on the lower surface of thevise.

ing operations. u The; end I43 of the rocker I40 opposite the bearingsurface I44 istapered downwardly and prevents operationofthe pump of theline forming and type casting machine forcing'the casting metal throughthe mold spouts whenthematrices are not packed tightly between the jawsof the The right jaw 15 of the vise is attached to the base 14 by-meansof aparallel linkage I36.

"The linkage I36 is adapted to allowupward movement of the jaw.15 whenhorizontal pressure is exerted against its vertical face I31. Since thisattachment is designed for automatic left or right quadding o'f'shortlinesgboth of the jaws and 1,5 are provided withelongatedhorizontal arms I38 and I39, respectively, which block the mold front,not. shown, into which mold the molten metal passes from spouts in itsrear during the casting operation. v

A rocker I40 is supported directly above the arm I39 of movable jaw by;means of a pin 3 I42 extending from a bracket I43 which is rigidly asupported from the line assembling andtype casting machine in-anysuitable manner. The

rocker I has a bearing surface I44- which is i urged against the uppersurface of arm I33 by acompressed springl45; Since the jaw 15 moveshorizontally, rocker -I40 isin a posiiton to be operated by the arlrnliitof the jaw 15 regardless of its movement during the quadding andcenterengages a post I41 extending from a pump stop lever systemindicated generally by I48. The

pump stop lever system is of the conventional type employed by the lineformingand type casting machines nowavailable and permits'operation ofthe casting pump when the post I41 has been displaced from its normalposition. The

jaw 15 is illustrated in Figure 6 in theraised position in which thepump stop lever is :displaced from the normal position.

When the justification lever rises to justify the assembled matricesheld between the vise jaws 10 and 15, movement of the spacebands in theassembled line of matrices will exert a force against theface' I31 ofjaw 15. Similarly; force is exerted by the wedging action of the pawls90 and/or 9| aspreviously described. This force will movethe jaw 15upwardlyon parallel linkage I36, and the upper surface of the arm I33will raise the bearing surface I44 ofthe" rocking arm I40. The taperedend I46 of the rocker I40 will then rotate downwardly and will displacepost "I41 to the left in Figure 6, and the pump stop lever'system I48 toallowv the pump to operate.

The attachment comprising this invention will be used the great majorityof the time for the leftquadding operationwith' the selector handle 19set at position on the selector scale; In this position the pawl 90 willengage the rack 51 to lock the left'jaw10 firmly in position; The

spur gears 55 and 51 will be disengaged to allow shaft 53 to turn'whileshaft 58 rem ains stationary. The slide'clamp'33 is then adjusted; to bespaced from the'rod 29 any distance which the operator ofthemachineprefersto allow justifica- 2 10 tion by expansion of thespacebands in the assembled line of matrices. Ordinarily, in a 30- picameasure the spacebands will allow expansion of about 3 picas. 7

If a line of matrices extending to a point within the expansionallowance is assembled, the assembler of the line forming machine willmove expansion rod 32 to the left and the slide clamp 33 will bearagainst the rod 29 and actuate arm 25 which, through lever 24, moves theguide It to the right. As the elevator descends, the guide pin I1 isdirected into the guide I6 and rotates arm I8 which moves the trippingfinger 22 to the right to a position where it will not engage the uppersurface I3 of the plunger I2. Thus the catch II on the plunger I2 holdsthe operating bar in position and the attachment does not operate when aline within the expansion allowance is assembledf The brake 42 engagingthe face of the guide It exerts sufficient braking force to hold theguide It against the force of spring 35 as the elevator descends andthereby maintains the tripping finger 22 in the nonoperation position.

If a short line-is assembled, the slide clamp 33 will not engage rod 29,and the guide I6 will be left in the normal position. As the elevatordescends, the guide pin "will enter the guide I0 and direct the trippingfinger 22 against the upper surface of the plunger I2 to depress theplunger and release the operating bar 2 for movement to the left; Sincethe spring 5 is attached to the elevator,'it will be under tension asthe elevator descends'and will exert a force urging the operating bar 2and driving rack 4 to the left. The rack 4 will engage the pinion gear 5which turns the shaft 53 to movethe jaw 15 until it engages theassembled matrices to accomplish the left quadding operation. As thevise closing lever I30 rises, as controlled by the timing mechanism ofthe type casting machine, the pawl 9| 'will engage the rack 12 and lockthe right jaw in place. The justification bar of the'machine will engagethe spacebands between the matrices for justification of the assembledline. Wedging action of the pawls 90 and SI, previously described-, alsoeffects justification, with or with out spacebands. Either will exert aforce against the face I31 of the jaw 15 to release the pump stop andallow the completion of the casting operation. After the castingoperation, the elevator will rise and the cam 45 will engage the roller46 to return the operating bar 2 to the cocked position. The cam 45 willalso engage the head 44 on the arm of the brake 42 to allow freemovement of the guide I6. 7

The attachment of the spring 6 to the elevator allows the tension on thespring to be released as the elevator starts to ascend. In this manner,the force urging the jaws together is released after casting to alloweasy removal of measure, the stop41 is set to control the amountofmovement of operating bar 2.

When the i plunger I2 is depressed to release the operating bar 2, thebar 2 will then move until it engages the end of the stop 41 and a lineof a definite measure will be formed.

The adjustments herein described allow auton'iatic'oentering andquadding of short lines and matriee's which have been assembled in atype casting machine. It thus becomes unnecessary for the operator ofthe machine to fill the lines with quads and the time required foroasting type; especially in closing paragraphs and centering headings,is greatly reduced.

While this invention has been described-in detail with respectto'aparticular modification of the automatic qu'adding and centeringattachfifent,-it is to'be understood that the concept of this" inventionis' not limitedto' those details ,-but

is determined by the scope of the appended claims;
